v0.25.14: rename Drive raw-read API to remove third-party project breadcrumbs

Pure rename pass — no behavioral change:
- Drive::is_libredrive_active() → Drive::is_raw_read_active()
- PlatformDriver::is_libredrive_active() trait method (same rename)
- Mt1959 struct field libredrive_active → raw_read_active
- Error::AacsLibredriveUnsupported → Error::AacsRawReadUnsupported
  (numeric code E7016 unchanged)
- All callers, tests, and doc comments updated to the new name.

Old identifiers removed entirely; downstream consumers must update.
Mirrored in bdemu, freemkv, autorip, freemkv-tools.

+### Changed
+
+- `Drive::is_libredrive_active()` renamed to `Drive::is_raw_read_active()`.
+  Same semantics; old name removed. Mirrored on the internal
+  `PlatformDriver::is_libredrive_active()` trait method (now
+  `is_raw_read_active()`).
+- `Error::AacsLibredriveUnsupported` renamed to
+  `Error::AacsRawReadUnsupported`; the underlying numeric code (E7016)
+  is unchanged. The `E_AACS_LIBREDRIVE_UNSUPPORTED` constant is
+  renamed to `E_AACS_RAW_READ_UNSUPPORTED`.
+
+No behavioural change — purely a rename pass.
